8. Although synchronize_rcu() is a bit slower than is call_rcu(),

- is important or the updaters cannot block, synchronize_rcu()
- should be used in preference to call_rcu().
+ it usually results in simpler code. So, unless update
+ performance is critically important or the updaters cannot block,
+ synchronize_rcu() should be used in preference to call_rcu().
+
+ An especially important property of the synchronize_rcu()
+ primitive is that it automatically self-limits: if grace periods
+ are delayed for whatever reason, then the synchronize_rcu()
+ primitive will correspondingly delay updates. In contrast,
+ code using call_rcu() should explicitly limit update rate in
+ cases where grace periods are delayed, as failing to do so can
+ result in excessive realtime latencies or even OOM conditions.
+
+ Ways of gaining this self-limiting property when using call_rcu()
+ include:
+
+ a. Keeping a count of the number of data-structure elements
+ used by the RCU-protected data structure, including those
+ waiting for a grace period to elapse. Enforce a limit
+ on this number, stalling updates as needed to allow
+ previously deferred frees to complete.
+
+ Alternatively, limit only the number awaiting deferred
+ free rather than the total number of elements.
+
+ b. Limiting update rate. For example, if updates occur only
+ once per hour, then no explicit rate limiting is required,
+ unless your system is already badly broken. The dcache
+ subsystem takes this approach -- updates are guarded
+ by a global lock, limiting their rate.
+
+ c. Trusted update -- if updates can only be done manually by
+ superuser or some other trusted user, then it might not
+ be necessary to automatically limit them. The theory
+ here is that superuser already has lots of ways to crash
+ the machine.
+
+ d. Use call_rcu_bh() rather than call_rcu(), in order to take
+ advantage of call_rcu_bh()'s faster grace periods.
+
+ e. Periodically invoke synchronize_rcu(), permitting a limited
+ number of updates per grace period.
9. All RCU list-traversal primitives, which include
list_for_each_rcu(), list_for_each_entry_rcu(),

after all ongoing RCU read-side critical sections have completed.
This callback variant is particularly useful in situations where

+
+ However, the call_rcu() API should not be used lightly, as use

+ In addition, the synchronize_rcu() API has the nice property
+ of automatically limiting update rate should grace periods
+ be delayed. This property results in system resilience in face
+ of denial-of-service attacks. Code using call_rcu() should limit
+ update rate in order to gain this same sort of resilience. See
+ checklist.txt for some approaches to limiting the update rate.

option in /etc/fstab, which is not discussed here.
+Filesystem connection:
+
+ A connection between the filesystem daemon and the kernel. The
+ connection exists until either the daemon dies, or the filesystem is

+ does _not_ break the connection, in this case it will exist until

The user who does the mounting.
The default is infinite. Note that the size of read requests is
limited anyway to 32 pages (which is 128kbyte on i386).
-Sysfs
-~~~~~
+Control filesystem
+~~~~~~~~~~~~~~~~~~
+
+There's a control filesystem for FUSE, which can be mounted by:
-FUSE sets up the following hierarchy in sysfs:
+ mount -t fusectl none /sys/fs/fuse/connections
- /sys/fs/fuse/connections/N/
+Mounting it under the '/sys/fs/fuse/connections' directory makes it
+backwards compatible with earlier versions.
-where N is an increasing number allocated to each new connection.
+Under the fuse control filesystem each connection has a directory
+named by a unique number.
-For each connection the following attributes are defined:
+For each connection the following files exist within this directory:
'waiting'
connection. This means that all waiting requests will be aborted an
error returned for all aborted and new requests.
-Only a privileged user may read or write these attributes.
+Only the owner of the mount may read or write these files.
+
+Interrupting filesystem operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a process issuing a FUSE filesystem request is interrupted, the
+following will happen:
+
+ 1) If the request is not yet sent to userspace AND the signal is
+ fatal (SIGKILL or unhandled fatal signal), then the request is
+ dequeued and returns immediately.
+
+ 2) If the request is not yet sent to userspace AND the signal is not
+ fatal, then an 'interrupted' flag is set for the request. When
+ the request has been successfully transfered to userspace and
+ this flag is set, an INTERRUPT request is queued.
+
+ 3) If the request is already sent to userspace, then an INTERRUPT
+ request is queued.
+
+INTERRUPT requests take precedence over other requests, so the
+userspace filesystem will receive queued INTERRUPTs before any others.
+
+The userspace filesystem may ignore the INTERRUPT requests entirely,
+or may honor them by sending a reply to the _original_ request, with
+the error set to EINTR.
+
+It is also possible that there's a race between processing the
+original request and it's INTERRUPT request. There are two possibilities:
+
+ 1) The INTERRUPT request is processed before the original request is
+ processed
+
+ 2) The INTERRUPT request is processed after the original request has
+ been answered
+
+If the filesystem cannot find the original request, it should wait for
+some timeout and/or a number of new requests to arrive, after which it
+should reply to the INTERRUPT request with an EAGAIN error. In case
+1) the INTERRUPT request will be requeued. In case 2) the INTERRUPT
+reply will be ignored.
Aborting a filesystem connection
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Use forced umount (umount -f). Works in all cases but only if
filesystem is still attached (it hasn't been lazy unmounted)
- - Abort filesystem through the sysfs interface. Most powerful
- method, always works.
+ - Abort filesystem through the FUSE control filesystem. Most
+ powerful method, always works.
How do non-privileged mounts work?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| | for "file"]
| | *DEADLOCK*
-The solution for this is to allow requests to be interrupted while
-they are in userspace:
-
- | [interrupted by signal] |
- | <fuse_unlink() |
- | [release semaphore] | [semaphore acquired]
- | <sys_unlink() |
- | | >fuse_unlink()
- | | [queue req on fc->pending]
- | | [wake up fc->waitq]
- | | [sleep on req->waitq]
-
-If the filesystem daemon was single threaded, this will stop here,
-since there's no other thread to dequeue and execute the request.
-In this case the solution is to kill the FUSE daemon as well. If
-there are multiple serving threads, you just have to kill them as
-long as any remain.
-
-Moral: a filesystem which deadlocks, can soon find itself dead.
+The solution for this is to allow the filesystem to be aborted.
Scenario 2 - Tricky deadlock
----------------------------
| | [lock page]
| | * DEADLOCK *
-Solution is again to let the the request be interrupted (not
-elaborated further).
-
-An additional problem is that while the write buffer is being
-copied to the request, the request must not be interrupted. This
-is because the destination address of the copy may not be valid
-after the request is interrupted.
-
-This is solved with doing the copy atomically, and allowing
-interruption while the page(s) belonging to the write buffer are
-faulted with get_user_pages(). The 'req->locked' flag indicates
-when the copy is taking place, and interruption is delayed until
-this flag is unset.
+Solution is basically the same as above.
-Scenario 3 - Tricky deadlock with asynchronous read
----------------------------------------------------
+An additional problem is that while the write buffer is being copied
+to the request, the request must not be interrupted/aborted. This is
+because the destination address of the copy may not be valid after the
+request has returned.
-The same situation as above, except thread-1 will wait on page lock
-and hence it will be uninterruptible as well. The solution is to
-abort the connection with forced umount (if mount is attached) or
-through the abort attribute in sysfs.
+This is solved with doing the copy atomically, and allowing abort

What is rootfs?
---------------
-Rootfs is a special instance of ramfs, which is always present in 2.6 systems.

-kernel's doubly-linked list of mount points.)
+Rootfs is a special instance of ramfs (or tmpfs, if that's enabled), which is

+to check for and handle an empty list, it's smaller and simpler for the kernel
+to just make sure certain lists can't become empty.

+
+Note: The cpio man page contains some bad advice that will break your initramfs
+archive if you follow it. It says "A typical way to generate the list
+of filenames is with the find command; you should give find the -depth option
+to minimize problems with permissions on directories that are unwritable or not
+searchable." Don't do this when creating initramfs.cpio.gz images, it won't
+work. The Linux kernel cpio extractor won't create files in a directory that
+doesn't exist, so the directory entries must go before the files that go in
+those directories. The above script gets them in the right order.
+
+External initramfs images:
+--------------------------
+
+If the kernel has initrd support enabled, an external cpio.gz archive can also
+be passed into a 2.6 kernel in place of an initrd. In this case, the kernel
+will autodetect the type (initramfs, not initrd) and extract the external cpio
+archive into rootfs before trying to run /init.
+
+This has the memory efficiency advantages of initramfs (no ramdisk block
+device) but the separate packaging of initrd (which is nice if you have
+non-GPL code you'd like to run from initramfs, without conflating it with
+the GPL licensed Linux kernel binary).
+
+It can also be used to supplement the kernel's built-in initamfs image. The
+files in the external archive will overwrite any conflicting files in
+the built-in initramfs archive. Some distributors also prefer to customize
+a single kernel image with task-specific initramfs images, without recompiling.
+
Contents of initramfs:
----------------------
+An initramfs archive is a complete self-contained root filesystem for Linux.
If you don't already understand what shared libraries, devices, and paths
you need to get a minimal root filesystem up and running, here are some
references:
I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net)
myself. These are LGPL and GPL, respectively. (A self-contained initramfs
-package is planned for the busybox 1.2 release.)
+package is planned for the busybox 1.3 release.)
In theory you could use glibc, but that's not well suited for small embedded
uses like this. (A "hello world" program statically linked against glibc is
over 400k. With uClibc it's 7k. Also note that glibc dlopens libnss to do
name lookups, even when otherwise statically linked.)
+A good first step is to get initramfs to run a statically linked "hello world"
+program as init, and test it under an emulator like qemu (www.qemu.org) or
+User Mode Linux, like so:
+
+ cat > hello.c << EOF
+ #include <stdio.h>
+ #include <unistd.h>
+
+ int main(int argc, char *argv[])
+ {
+ printf("Hello world!\n");
+ sleep(999999999);
+ }
+ EOF
+ gcc -static hello2.c -o init
+ echo init | cpio -o -H newc | gzip > test.cpio.gz
+ # Testing external initramfs using the initrd loading mechanism.
+ qemu -kernel /boot/vmlinuz -initrd test.cpio.gz /dev/zero
+
+When debugging a normal root filesystem, it's nice to be able to boot with
+"init=/bin/sh". The initramfs equivalent is "rdinit=/bin/sh", and it's
+just as useful.
+
Why cpio rather than tar?

-Documentation for kdump - the kexec-based crash dumping solution
+================================================================
+Documentation for Kdump - The kexec-based Crash Dumping Solution
================================================================
-DESIGN
-======
+This document includes overview, setup and installation, and analysis
+information.
-Kdump uses kexec to reboot to a second kernel whenever a dump needs to be
-taken. This second kernel is booted with very little memory. The first kernel
-reserves the section of memory that the second kernel uses. This ensures that
-on-going DMA from the first kernel does not corrupt the second kernel.
+Overview
+========
-All the necessary information about Core image is encoded in ELF format and
-stored in reserved area of memory before crash. Physical address of start of
-ELF header is passed to new kernel through command line parameter elfcorehdr=.
+Kdump uses kexec to quickly boot to a dump-capture kernel whenever a
+dump of the system kernel's memory needs to be taken (for example, when
+the system panics). The system kernel's memory image is preserved across
+the reboot and is accessible to the dump-capture kernel.
-On i386, the first 640 KB of physical memory is needed to boot, irrespective
-of where the kernel loads. Hence, this region is backed up by kexec just before
-rebooting into the new kernel.
+You can use common Linux commands, such as cp and scp, to copy the
+memory image to a dump file on the local disk, or across the network to
+a remote system.
-In the second kernel, "old memory" can be accessed in two ways.
+Kdump and kexec are currently supported on the x86, x86_64, and ppc64
+architectures.
-- The first one is through a /dev/oldmem device interface. A capture utility
- can read the device file and write out the memory in raw format. This is raw
- dump of memory and analysis/capture tool should be intelligent enough to
- determine where to look for the right information. ELF headers (elfcorehdr=)
- can become handy here.
+When the system kernel boots, it reserves a small section of memory for
+the dump-capture kernel. This ensures that ongoing Direct Memory Access
+(DMA) from the system kernel does not corrupt the dump-capture kernel.
+The kexec -p command loads the dump-capture kernel into this reserved
+memory.
-- The second interface is through /proc/vmcore. This exports the dump as an ELF
- format file which can be written out using any file copy command
- (cp, scp, etc). Further, gdb can be used to perform limited debugging on
- the dump file. This method ensures methods ensure that there is correct
- ordering of the dump pages (corresponding to the first 640 KB that has been
- relocated).
+On x86 machines, the first 640 KB of physical memory is needed to boot,
+regardless of where the kernel loads. Therefore, kexec backs up this
+region just before rebooting into the dump-capture kernel.
-SETUP
-=====
+All of the necessary information about the system kernel's core image is
+encoded in the ELF format, and stored in a reserved area of memory
+before a crash. The physical address of the start of the ELF header is
+passed to the dump-capture kernel through the elfcorehdr= boot
+parameter.
+
+With the dump-capture kernel, you can access the memory image, or "old
+memory," in two ways:
+
+- Through a /dev/oldmem device interface. A capture utility can read the
+ device file and write out the memory in raw format. This is a raw dump
+ of memory. Analysis and capture tools must be intelligent enough to
+ determine where to look for the right information.
+
+- Through /proc/vmcore. This exports the dump as an ELF-format file that
+ you can write out using file copy commands such as cp or scp. Further,
+ you can use analysis tools such as the GNU Debugger (GDB) and the Crash
+ tool to debug the dump file. This method ensures that the dump pages are
+ correctly ordered.
+
+
+Setup and Installation
+======================
+
+Install kexec-tools and the Kdump patch
+---------------------------------------
+
+1) Login as the root user.
+
+2) Download the kexec-tools user-space package from the following URL:
+
+ http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz
+
+3) Unpack the tarball with the tar command, as follows:
+
+ tar xvpzf kexec-tools-1.101.tar.gz
+
+4) Download the latest consolidated Kdump patch from the following URL:
+
+ http://lse.sourceforge.net/kdump/
+
+ (This location is being used until all the user-space Kdump patches
+ are integrated with the kexec-tools package.)
+
+5) Change to the kexec-tools-1.101 directory, as follows:
+
+ cd kexec-tools-1.101
+
+6) Apply the consolidated patch to the kexec-tools-1.101 source tree
+ with the patch command, as follows. (Modify the path to the downloaded
+ patch as necessary.)
+
+ patch -p1 < /path-to-kdump-patch/kexec-tools-1.101-kdump.patch
+
+7) Configure the package, as follows:
+
+ ./configure
+
+8) Compile the package, as follows:
+
+ make
+
+9) Install the package, as follows:
+
+ make install
+
+
+Download and build the system and dump-capture kernels
+------------------------------------------------------
+
+Download the mainline (vanilla) kernel source code (2.6.13-rc1 or newer)
+from http://www.kernel.org. Two kernels must be built: a system kernel
+and a dump-capture kernel. Use the following steps to configure these
+kernels with the necessary kexec and Kdump features:
+
+System kernel
+-------------
+
+1) Enable "kexec system call" in "Processor type and features."
+
+ CONFIG_KEXEC=y
+
+2) Enable "sysfs file system support" in "Filesystem" -> "Pseudo
+ filesystems." This is usually enabled by default.
+
+ CONFIG_SYSFS=y
+
+ Note that "sysfs file system support" might not appear in the "Pseudo
+ filesystems" menu if "Configure standard kernel features (for small
+ systems)" is not enabled in "General Setup." In this case, check the
+ .config file itself to ensure that sysfs is turned on, as follows:
+
+ grep 'CONFIG_SYSFS' .config
+
+3) Enable "Compile the kernel with debug info" in "Kernel hacking."
+
+ CONFIG_DEBUG_INFO=Y
+
+ This causes the kernel to be built with debug symbols. The dump
+ analysis tools require a vmlinux with debug symbols in order to read
+ and analyze a dump file.
+
+4) Make and install the kernel and its modules. Update the boot loader
+ (such as grub, yaboot, or lilo) configuration files as necessary.
+
+5) Boot the system kernel with the boot parameter "crashkernel=Y@X",
+ where Y specifies how much memory to reserve for the dump-capture kernel
+ and X specifies the beginning of this reserved memory. For example,
+ "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory
+ starting at physical address 0x01000000 for the dump-capture kernel.
+
+ On x86 and x86_64, use "crashkernel=64M@16M".
+
+ On ppc64, use "crashkernel=128M@32M".
+
+
+The dump-capture kernel
+-----------------------
-1) Download the upstream kexec-tools userspace package from
- http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz.
-
- Apply the latest consolidated kdump patch on top of kexec-tools-1.101
- from http://lse.sourceforge.net/kdump/. This arrangment has been made
- till all the userspace patches supporting kdump are integrated with
- upstream kexec-tools userspace.
-
-2) Download and build the appropriate (2.6.13-rc1 onwards) vanilla kernels.
- Two kernels need to be built in order to get this feature working.
- Following are the steps to properly configure the two kernels specific
- to kexec and kdump features:
-
- A) First kernel or regular kernel:
- ----------------------------------
- a) Enable "kexec system call" feature (in Processor type and features).
- CONFIG_KEXEC=y
- b) Enable "sysfs file system support" (in Pseudo filesystems).
- CONFIG_SYSFS=y
- c) make
- d) Boot into first kernel with the command line parameter "crashkernel=Y@X".
- Use appropriate values for X and Y. Y denotes how much memory to reserve
- for the second kernel, and X denotes at what physical address the
- reserved memory section starts. For example: "crashkernel=64M@16M".
-
-
- B) Second kernel or dump capture kernel:
- ---------------------------------------
- a) For i386 architecture enable Highmem support
- CONFIG_HIGHMEM=y
- b) Enable "kernel crash dumps" feature (under "Processor type and features")
- CONFIG_CRASH_DUMP=y
- c) Make sure a suitable value for "Physical address where the kernel is
- loaded" (under "Processor type and features"). By default this value
- is 0x1000000 (16MB) and it should be same as X (See option d above),
- e.g., 16 MB or 0x1000000.
- CONFIG_PHYSICAL_START=0x1000000
- d) Enable "/proc/vmcore support" (Optional, under "Pseudo filesystems").
- CONFIG_PROC_VMCORE=y
-
-3) After booting to regular kernel or first kernel, load the second kernel
- using the following command:
-
- kexec -p <second-kernel> --args-linux --elf32-core-headers
- --append="root=<root-dev> init 1 irqpoll maxcpus=1"
-
- Notes:
- ======
- i) <second-kernel> has to be a vmlinux image ie uncompressed elf image.
- bzImage will not work, as of now.
- ii) --args-linux has to be speicfied as if kexec it loading an elf image,
- it needs to know that the arguments supplied are of linux type.
- iii) By default ELF headers are stored in ELF64 format to support systems
- with more than 4GB memory. Option --elf32-core-headers forces generation
- of ELF32 headers. The reason for this option being, as of now gdb can
- not open vmcore file with ELF64 headers on a 32 bit systems. So ELF32
- headers can be used if one has non-PAE systems and hence memory less
- than 4GB.
- iv) Specify "irqpoll" as command line parameter. This reduces driver
- initialization failures in second kernel due to shared interrupts.
- v) <root-dev> needs to be specified in a format corresponding to the root
- device name in the output of mount command.
- vi) If you have built the drivers required to mount root file system as
- modules in <second-kernel>, then, specify
- --initrd=<initrd-for-second-kernel>.
- vii) Specify maxcpus=1 as, if during first kernel run, if panic happens on
- non-boot cpus, second kernel doesn't seem to be boot up all the cpus.
- The other option is to always built the second kernel without SMP
- support ie CONFIG_SMP=n
-
-4) After successfully loading the second kernel as above, if a panic occurs
- system reboots into the second kernel. A module can be written to force
- the panic or "ALT-SysRq-c" can be used initiate a crash dump for testing
- purposes.
-
-5) Once the second kernel has booted, write out the dump file using
+1) Under "General setup," append "-kdump" to the current string in
+ "Local version."
+
+2) On x86, enable high memory support under "Processor type and
+ features":
+
+ CONFIG_HIGHMEM64G=y
+ or
+ CONFIG_HIGHMEM4G
+
+3) On x86 and x86_64, disable symmetric multi-processing support
+ under "Processor type and features":
+
+ CONFIG_SMP=n
+ (If CONFIG_SMP=y, then specify maxcpus=1 on the kernel command line
+ when loading the dump-capture kernel, see section "Load the Dump-capture
+ Kernel".)
+
+4) On ppc64, disable NUMA support and enable EMBEDDED support:
+
+ CONFIG_NUMA=n
+ CONFIG_EMBEDDED=y
+ CONFIG_EEH=N for the dump-capture kernel
+
+5) Enable "kernel crash dumps" support under "Processor type and
+ features":
+
+ CONFIG_CRASH_DUMP=y
+
+6) Use a suitable value for "Physical address where the kernel is
+ loaded" (under "Processor type and features"). This only appears when
+ "kernel crash dumps" is enabled. By default this value is 0x1000000
+ (16MB). It should be the same as X in the "crashkernel=Y@X" boot
+ parameter discussed above.
+
+ On x86 and x86_64, use "CONFIG_PHYSICAL_START=0x1000000".
+
+ On ppc64 the value is automatically set at 32MB when
+ CONFIG_CRASH_DUMP is set.
+
+6) Optionally enable "/proc/vmcore support" under "Filesystems" ->
+ "Pseudo filesystems".
+
+ CONFIG_PROC_VMCORE=y
+ (CONFIG_PROC_VMCORE is set by default when CONFIG_CRASH_DUMP is selected.)
+
+7) Make and install the kernel and its modules. DO NOT add this kernel
+ to the boot loader configuration files.
+
+
+Load the Dump-capture Kernel
+============================
+
+After booting to the system kernel, load the dump-capture kernel using
+the following command:
+
+ kexec -p <dump-capture-kernel> \
+ --initrd=<initrd-for-dump-capture-kernel> --args-linux \
+ --append="root=<root-dev> init 1 irqpoll"
+
+
+Notes on loading the dump-capture kernel:
+
+* <dump-capture-kernel> must be a vmlinux image (that is, an
+ uncompressed ELF image). bzImage does not work at this time.
+
+* By default, the ELF headers are stored in ELF64 format to support
+ systems with more than 4GB memory. The --elf32-core-headers option can
+ be used to force the generation of ELF32 headers. This is necessary
+ because GDB currently cannot open vmcore files with ELF64 headers on
+ 32-bit systems. ELF32 headers can be used on non-PAE systems (that is,
+ less than 4GB of memory).
+
+* The "irqpoll" boot parameter reduces driver initialization failures
+ due to shared interrupts in the dump-capture kernel.
+
+* You must specify <root-dev> in the format corresponding to the root
+ device name in the output of mount command.
+
+* "init 1" boots the dump-capture kernel into single-user mode without
+ networking. If you want networking, use "init 3."
+
+
+Kernel Panic
+============
+
+After successfully loading the dump-capture kernel as previously
+described, the system will reboot into the dump-capture kernel if a
+system crash is triggered. Trigger points are located in panic(),
+die(), die_nmi() and in the sysrq handler (ALT-SysRq-c).
+
+The following conditions will execute a crash trigger point:
+
+If a hard lockup is detected and "NMI watchdog" is configured, the system
+will boot into the dump-capture kernel ( die_nmi() ).
+
+If die() is called, and it happens to be a thread with pid 0 or 1, or die()
+is called inside interrupt context or die() is called and panic_on_oops is set,
+the system will boot into the dump-capture kernel.
+
+On powererpc systems when a soft-reset is generated, die() is called by all cpus and the system system will boot into the dump-capture kernel.
+
+For testing purposes, you can trigger a crash by using "ALT-SysRq-c",
+"echo c > /proc/sysrq-trigger or write a module to force the panic.
+
+Write Out the Dump File
+=======================
+
+After the dump-capture kernel is booted, write out the dump file with
+the following command:
cp /proc/vmcore <dump-file>
- Dump memory can also be accessed as a /dev/oldmem device for a linear/raw
- view. To create the device, type:
+You can also access dumped memory as a /dev/oldmem device for a linear
+and raw view. To create the device, use the following command:
- mknod /dev/oldmem c 1 12

- Use "dd" with suitable options for count, bs and skip to access specific
- portions of the dump.

+This page describes how to make calls to the firmware api.
+
+How to call
+===========
+
+The preferred calling convention is known as the firmware mailbox. The
+mailboxes are basically a fixed length array that serves as the call-stack.
+
+Firmware mailboxes can be located by searching the encoder and decoder memory
+for a 16 byte signature. That signature will be located on a 256-byte boundary.
+
+Signature:
+0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
+0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
+
+The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
+reserved for API calls. The second 10 are used by the firmware for event
+notification.
+
+ Index Name
+ ----- ----
+ 0 Flags
+ 1 Command
+ 2 Return value
+ 3 Timeout
+ 4-19 Parameter/Result
+
+
+The flags are defined in the following table. The direction is from the
+perspective of the firmware.
+
+ Bit Direction Purpose
+ --- --------- -------
+ 2 O Firmware has processed the command.
+ 1 I Driver has finished setting the parameters.
+ 0 I Driver is using this mailbox.
+
+
+The command is a 32-bit enumerator. The API specifics may be found in the
+fw-*-api.txt documents.
+
+The return value is a 32-bit enumerator. Only two values are currently defined:
+0=success and -1=command undefined.
+
+There are 16 parameters/results 32-bit fields. The driver populates these fields
+with values for all the parameters required by the call. The driver overwrites
+these fields with result values returned by the call. The API specifics may be
+found in the fw-*-api.txt documents.
+
+The timeout value protects the card from a hung driver thread. If the driver
+doesn't handle the completed call within the timeout specified, the firmware
+will reset that mailbox.
+
+To make an API call, the driver iterates over each mailbox looking for the
+first one available (bit 0 has been cleared). The driver sets that bit, fills
+in the command enumerator, the timeout value and any required parameters. The
+driver then sets the parameter ready bit (bit 1). The firmware scans the
+mailboxes for pending commands, processes them, sets the result code, populates
+the result value array with that call's return values and sets the call
+complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
+and clear all the flags. If the driver does not perform this task within the
+time set in the timeout register, the firmware will reset that mailbox.
+
+Event notifications are sent from the firmware to the host. The host tells the
+firmware which events it is interested in via an API call. That call tells the
+firmware which notification mailbox to use. The firmware signals the host via
+an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
+value and Timeout words are not used.

+This page describes the structures and procedures used by the cx2341x DMA
+engine.
+
+Introduction
+============
+
+The cx2341x PCI interface is busmaster capable. This means it has a DMA
+engine to efficiently transfer large volumes of data between the card and main
+memory without requiring help from a CPU. Like most hardware, it must operate
+on contiguous physical memory. This is difficult to come by in large quantities
+on virtual memory machines.
+
+Therefore, it also supports a technique called "scatter-gather". The card can
+transfer multiple buffers in one operation. Instead of allocating one large
+contiguous buffer, the driver can allocate several smaller buffers.
+
+In practice, I've seen the average transfer to be roughly 80K, but transfers
+above 128K were not uncommon, particularly at startup. The 128K figure is
+important, because that is the largest block that the kernel can normally
+allocate. Even still, 128K blocks are hard to come by, so the driver writer is
+urged to choose a smaller block size and learn the scatter-gather technique.
+
+Mailbox #10 is reserved for DMA transfer information.
+
+Flow
+====
+
+This section describes, in general, the order of events when handling DMA
+transfers. Detailed information follows this section.
+
+- The card raises the Encoder interrupt.
+- The driver reads the transfer type, offset and size from Mailbox #10.
+- The driver constructs the scatter-gather array from enough free dma buffers
+ to cover the size.
+- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
+- The card raises the DMA Complete interrupt.
+- The driver checks the DMA status register for any errors.
+- The driver post-processes the newly transferred buffers.
+
+NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
+simultaneously. (End of the last, start of the next, etc.)
+
+Mailbox #10
+===========
+
+The Flags, Command, Return Value and Timeout fields are ignored.
+
+Name: Mailbox #10
+Results[0]: Type: 0: MPEG.
+Results[1]: Offset: The position relative to the card's memory space.
+Results[2]: Size: The exact number of bytes to transfer.
+
+My speculation is that since the StartCapture API has a capture type of "RAW"
+available, that the type field will have other values that correspond to YUV
+and PCM data.
+
+Scatter-Gather Array
+====================
+
+The scatter-gather array is a contiguously allocated block of memory that
+tells the card the source and destination of each data-block to transfer.
+Card "addresses" are derived from the offset supplied by Mailbox #10. Host
+addresses are the physical memory location of the target DMA buffer.
+
+Each S-G array element is a struct of three 32-bit words. The first word is
+the source address, the second is the destination address. Both take up the
+entire 32 bits. The lowest 16 bits of the third word is the transfer byte
+count. The high-bit of the third word is the "last" flag. The last-flag tells
+the card to raise the DMA_DONE interrupt. From hard personal experience, if
+you forget to set this bit, the card will still "work" but the stream will
+most likely get corrupted.
+
+The transfer count must be a multiple of 256. Therefore, the driver will need
+to track how much data in the target buffer is valid and deal with it
+accordingly.
+
+Array Element:
+
+- 32-bit Source Address
+- 32-bit Destination Address
+- 16-bit reserved (high bit is the last flag)
+- 16-bit byte count
+
+DMA Transfer Status
+===================
+
+Register 0x0004 holds the DMA Transfer Status:
+

+4 Scatter-Gather array error
+3 DMA write error
+2 DMA read error
+1 write completed

+This document describes the cx2341x memory map and documents some of the register
+space.
+
+Warning! This information was figured out from searching through the memory and
+registers, this information may not be correct and is certainly not complete, and
+was not derived from anything more than searching through the memory space with
+commands like:
+
+ ivtvctl -O min=0x02000000,max=0x020000ff
+
+So take this as is, I'm always searching for more stuff, it's a large
+register space :-).
+
+Memory Map
+==========
+
+The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
+(Base Address Register 0). The addresses here are offsets relative to the
+address held in BAR0.
+
+0x00000000-0x00ffffff Encoder memory space
+0x00000000-0x0003ffff Encode.rom
+ ???-??? MPEG buffer(s)
+ ???-??? Raw video capture buffer(s)
+ ???-??? Raw audio capture buffer(s)
+ ???-??? Display buffers (6 or 9)
+
+0x01000000-0x01ffffff Decoder memory space
+0x01000000-0x0103ffff Decode.rom

+
+0x02000000-0x0200ffff Register Space
+
+Registers
+=========
+
+The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
+All of these registers are 32 bits wide.
+
+DMA Registers 0x000-0xff:
+
+ 0x00 - Control:
+ 0=reset/cancel, 1=read, 2=write, 4=stop

+ 0x08 - pci DMA pointer for read link list
+ 0x0c - pci DMA pointer for write link list
+ 0x10 - read/write DMA enable:
+ 1=read enable, 2=write enable
+ 0x14 - always 0xffffffff, if set any lower instability occurs, 0x00 crashes
+ 0x18 - ??
+ 0x1c - always 0x20 or 32, smaller values slow down DMA transactions
+ 0x20 - always value of 0x780a010a
+ 0x24-0x3c - usually just random values???
+ 0x40 - Interrupt status
+ 0x44 - Write a bit here and shows up in Interrupt status 0x40
+ 0x48 - Interrupt Mask
+ 0x4C - always value of 0xfffdffff,
+ if changed to 0xffffffff DMA write interrupts break.
+ 0x50 - always 0xffffffff
+ 0x54 - always 0xffffffff (0x4c, 0x50, 0x54 seem like interrupt masks, are
+ 3 processors on chip, Java ones, VPU, SPU, APU, maybe these are the
+ interrupt masks???).
+ 0x60-0x7C - random values
+ 0x80 - first write linked list reg, for Encoder Memory addr
+ 0x84 - first write linked list reg, for pci memory addr
+ 0x88 - first write linked list reg, for length of buffer in memory addr
+ (|0x80000000 or this for last link)
+ 0x8c-0xcc - rest of write linked list reg, 8 sets of 3 total, DMA goes here
+ from linked list addr in reg 0x0c, firmware must push through or
+ something.
+ 0xe0 - first (and only) read linked list reg, for pci memory addr
+ 0xe4 - first (and only) read linked list reg, for Decoder memory addr
+ 0xe8 - first (and only) read linked list reg, for length of buffer
+ 0xec-0xff - Nothing seems to be in these registers, 0xec-f4 are 0x00000000.

+This document describes how to upload the cx2341x firmware to the card.
+
+How to find
+===========
+
+See the web pages of the various projects that uses this chip for information
+on how to obtain the firmware.
+
+The firmware stored in a Windows driver can be detected as follows:
+
+- Each firmware image is 256k bytes.
+- The 1st 32-bit word of the Encoder image is 0x0000da7
+- The 1st 32-bit word of the Decoder image is 0x00003a7
+- The 2nd 32-bit word of both images is 0xaa55bb66
+
+How to load
+===========
+
+- Issue the FWapi command to stop the encoder if it is running. Wait for the
+ command to complete.
+- Issue the FWapi command to stop the decoder if it is running. Wait for the
+ command to complete.
+- Issue the I2C command to the digitizer to stop emitting VSYNC events.
+- Issue the FWapi command to halt the encoder's firmware.
+- Sleep for 10ms.
+- Issue the FWapi command to halt the decoder's firmware.
+- Sleep for 10ms.
+- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
+- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
+- Write 0x00000000 to register 0xA064 to ping? the APU.
+- Write 0xFFFFFFFE to register 0x9058 to stop the VPU.
+- Write 0xFFFFFFFF to register 0x9054 to reset the HW blocks.
+- Write 0x00000001 to register 0x9050 to stop the SPU.
+- Sleep for 10ms.
+- Write 0x0000001A to register 0x07FC to init the Encoder SDRAM's pre-charge.
+- Write 0x80000640 to register 0x07F8 to init the Encoder SDRAM's refresh to 1us.
+- Write 0x0000001A to register 0x08FC to init the Decoder SDRAM's pre-charge.
+- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
+- Sleep for 512ms. (600ms is recommended)
+- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
+- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
+- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
+ re-enable the SPU.
+- Sleep for 1 second.
+- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058
+ to re-enable the VPU.
+- Sleep for 1 second.
+- Issue status API commands to both firmware images to verify.

+The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.

+
+>From the data sheet:
+ Register 24'h20004 PCI Interrupt Status
+ bit [18] IR_SMP_INT Set when 32 input samples have been collected over
+ gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+compat remote)
+set register 0x35C050 to 0xa80a80
+
+enable sampling
+set register 0x35C054 to 0x5
+
+Of course, enable the IRQ bit 18 in the interrupt mask register .(and
+provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is recieved.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data) An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well. Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.
+
+http://www.atmel.com/dyn/resources/prod_documents/doc2817.pdf
+This data sheet (google search) seems to have a lovely description of the
+RC5 basics
+
+http://users.pandora.be/nenya/electronics/rc5/ and more data
+
+http://www.ee.washington.edu/circuit_archive/text/ir_decode.txt

-
- FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed

- not set.
- FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode.
- FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have
- magic meaning to developers.
- FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen,
- useful only for debugging.
- FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers.
- FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as
- it was received from the camera.
- Default (not set) is to mix the
- preceding frame in to compensate
- for occasional loss of Isoc data
- on high frame rates.
- FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame
- prior to use; relevant only if
- FLAGS_SEPARATE_FRAMES is set.
- Default is not to clean frames,
- this is a little faster but may
- produce flicker if frame rate is
- too high and Isoc data gets lost.
- FLAGS_NO_DECODING 128 This flag turns the video stream
- decoder off, and dumps the raw
- Isoc data from the camera into
- the reading process. Useful to
- developers, but not to users.

framerate This setting controls frame rate of the camera. This is
- an approximate setting (in terms of "worst" ... "best")
- because camera changes frame rate depending on amount
- of light available. Setting 0 is slowest, 6 is fastest.
- Beware - fast settings are very demanding and may not
- work well with all video sizes. Be conservative.

hue_correction This highly optional setting allows to adjust the
- hue of the image in a way slightly different from
- what usual "hue" control does. Both controls affect
- YUV colorspace: regular "hue" control adjusts only
- U component, and this "hue_correction" option similarly
- adjusts only V component. However usually it is enough
- to tweak only U or V to compensate for colored light or
- color temperature; this option simply allows more
- complicated correction when and if it is necessary.

init_brightness These settings specify _initial_ values which will be
init_contrast used to set up the camera. If your V4L application has
init_color its own controls to adjust the picture then these
init_hue controls will be used too. These options allow you to
- preconfigure the camera when it gets connected, before
- any V4L application connects to it. Good for webcams.

init_model2_rg These initial settings alter color balance of the
init_model2_rg2 camera on hardware level. All four settings may be used
init_model2_yb settings only apply to Model 2 cameras.
lighting This option selects one of three hardware-defined
- photosensitivity settings of the camera. 0=bright light,
- 1=Medium (default), 2=Low light. This setting affects
- frame rate: the dimmer the lighting the lower the frame
- rate (because longer exposition time is needed). The
- Model 2 cameras allow values more than 2 for this option,
- thus enabling extremely high sensitivity at cost of frame
- rate, color saturation and imaging sensor noise.

- is most sharp. Be aware that CMOS sensor used in the
- camera is pretty noisy, so if you choose 6 you will

size This setting chooses one of several image sizes that are
- supported by this driver. Cameras may support more, but
- it's difficult to reverse-engineer all formats.
- Following video sizes are supported:
-
- size=0 128x96 (Model 1 only)
- size=1 160x120
- size=2 176x144
- size=3 320x240 (Model 2 only)
- size=4 352x240 (Model 2 only)
- size=5 352x288
- size=6 640x480 (Model 3 only)
-
- The 352x288 is the native size of the Model 1 sensor
- array, so it's the best resolution the camera can
- yield. The best resolution of Model 2 is 176x144, and
- larger images are produced by stretching the bitmap.
- Model 3 has sensor with 640x480 grid, and it works too,
- but the frame rate will be exceptionally low (1-2 FPS);
- it may be still OK for some applications, like security.
- Choose the image size you need. The smaller image can
- support faster frame rate. Default is 352x288.

/*
- * Unfortunately request interruption not just solves the deadlock
- * problem, it causes problems too. These stem from the fact, that an
- * interrupted request is continued to be processed in userspace,
- * while all the locks and object references (inode and file) held
- * during the operation are released.
- *
- * To release the locks is exactly why there's a need to interrupt the
- * request, so there's not a lot that can be done about this, except
- * introduce additional locking in userspace.
- *
- * More important is to keep inode and file references until userspace
- * has replied, otherwise FORGET and RELEASE could be sent while the
- * inode/file is still used by the filesystem.
- *
- * For this reason the concept of "background" request is introduced.
- * An interrupted request is backgrounded if it has been already sent
- * to userspace. Backgrounding involves getting an extra reference to
- * inode(s) or file used in the request, and adding the request to
- * fc->background list. When a reply is received for a background
- * request, the object references are released, and the request is
- * removed from the list. If the filesystem is unmounted while there
- * are still background requests, the list is walked and references
- * are released as if a reply was received.
+ * This function is called when a request is finished. Either a reply
+ * has arrived or it was aborted (and not yet sent) or some error
+ * occurred during communication with userspace, or the device file
+ * was closed. The requester thread is woken up (if still waiting),
+ * the 'end' callback is called if given, else the reference to the
+ * request is released
*
- * There's one more use for a background request. The RELEASE message is
- * always sent as background, since it doesn't return an error or
- * data.
+ * Called with fc->lock, unlocks it
